Variable Boundary Gain Compensation
Variable Boundary Gain Compensation is a fi lter which can compensate for bass
peaking which typically starts around 60Hz and increases downwards. At fi rst,
this effect sounds superfi cially impressive, but listen to music for any length of
time and it becomes “boomy” and rather annoying. The effect commonly occurs
in smaller rooms and when your listening position is near to a wall, hence the
name Boundary Gain Compensation.
As with phase adjustment, we recommend you play music or the test frequency
fi les from www.Jamo.com and have a friend turn the Variable Boundary Gain
Compensation control, while you sit in the listening area. Then simply adjust it
so that when the bass hits the lowest frequencies, there aren’t any detectable
bass peaks.
Cleaning
Please use a dust-free cloth to clean the speakers. It is also possible to use a slightly
damp cloth for more stubborn marks.
Under no circumstances should you use any kind of cleaning agent on, or in close
proximity to, these speakers.
